Based on the proceedings of an international conference held at the University of California (Berkeley) in May, 1968, this book contains papers on American professionals abroad and their training. The papers are aimed at providing professional self knowledge, and better awareness of the limits of professional knowledge; they examine the implications of this viewpoint for professional training and discuss institutional implications of undertaking action oriented research in developing countries. They discuss: (1) experts abroad, and the challenges and problems that they are confronted with; (2) concepts of profession planning; (3) education for world responsibility--training of economists for service in developing countries, guidelines for professional schools, and the integrated educational institution; and (4) international professional cooperation. An epilogue discussing professionals and development has been included. (Author/PT)
